    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 6:RMU  
    ?cBO6^  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: "8t\MKt(  
    enableservice('AutomationServer', true) 2 zl~>3S  
    enableservice('AutomationServer') |F~88j{VN  
    o_:Qk;t  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 Zi3T~:0p:  
     ("F)  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: =5_y<0`4  
    1. 在FRED脚本编辑界面找到参考. }@*I+\W/  
    2. 找到Matlab Automation Server Type Library E(/ sXji!  
    3. 将名字改为MLAPP rys<-i(

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 GXEcpc08

    现在将脚本代码公布如下,此脚本执行如下几个步骤: {|p"; uJ  
    1. 创建Matlab服务器。 ,]U[W  
    2. 移动探测面对于前一聚焦面的位置。 h+xA?[ c=  
    3. 在探测面追迹光线 o#dcD?^  
    4. 在探测面计算照度 D@5s8xv  
    5. 使用PutWorkspaceData发送照度数据到Matlab iha9!kf  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 _y-B";Vmm  
    7. 用Matlab画出照度数据 ~%KM3Vap  
    8. 在Matlab计算照度平均值 EJ8I[(  
    9. 返回数据到FRED中 `+fk`5Y
